Subject: Re: [iText-questions] Re garding JSP to PDF Conversion
Mike:
If I read it correctly, Bruno's point is that what you're describing is
*not* converting a JSP page to PDF. A JSP is a template with commands to the
servlet engine, bits of HTML, etc. Why would anyone turn a JSP file into a
PDF?
OK, presumably he isn't trying to use PDF to document their
JSP source code but I don't think anyone thought that :)
I guess I'm generally agreeing with Bruno but asking the larger question
of why people do a lot of what they do involving PDF.
Sure, taking your information directly in a one-step process
to generate your view seems like the best approach but this
question comes up in a variety of forms and it often
gets answered without further consideration of alternatives.
And, sure the question may not have reflected the OP's real interests
here and in other cases.
If you are dealing with graphical information however, a
JSP output can just as much be your data source as can any other
picture.
Maybe he is just documenting the quality of their JSP effort and wants
an automated process to generate a report on the JSP results so management
can look at samples from that. Maybe he needs an automated way to get screen
shots that are flagged as errors or he is generating a sales brochure
highlighting lots of JSP pages they have done?
Or, maybe he just has a lot of JSP that
needs to serve as the primary way of formatting a page and wants a pdf
that is consistent with it.
As I read it, the OP's question (if not taken literally) asks whether you
could use iText to write a servlet (or servlet engine) that would generate
PDFs using a JSP syntax.
The answer is sure. But why would you not use a reporting library, of which
there are dozens? That way you get a report as your PDF document rather than
the equivalent of a screen capture of an HTML page. And you have to write
very little of your own code.
Hope that helps.

Hi Everyone,

The page which we want to convert is retrieve data from database like
images and texts. So I want to convert the whole dynamic JSP page into
PDF format.
*sigh* You don't want to convert a JSP page to PDF format.
If you do, your architecture is bad, very bad. Please reconsider!
This is a recurring issue with PDF users but if you are going to defend
PDF as a general information publishing format, then why not
convert arbitrary rendered material into PDF? Just find some way to
capture
the rendered JSP pixels and store in PDF as a series of TIFF's?
Maybe JSP has some proprietary rendering or he just wants one consistent
piece of graphics generating code?
Obviously this is a bit cumbersome and simply serves to
obscure the source information, but people do it all the time
with PDF. So, I'm just suggesting that there could be as
good a reason to do this as use PDF for any other purpose for which
it is commonly used.
Does it happens in iText. Is there any facility available in
iText. If it is available please reply me.
